HULL CONSTRUCTION.

Application filed May 7,

This invention relates to hull construction, the primary object of the invention being' to so construct the hull as to permit the en'iployment of straight frame pieces, ribs and plankinpl members which are disposed at right angles to each other so that straight boards or timbers may be used without bending', curving` or otherwise shaping; them.

A further object is to provide a vhull construction in which the sides of the hull taper inwardly from their lower to their upper ends.

A further object is to provide a hull construction which is extremely simple and inexpensive to manufacture.

lVith these and other objects in view, the invention consists in cert-ain novel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure l is a plan view of my improved hull;

Figure 2 is a view in transverse section on the line 9.*2 of Figure l;

Figure 3 is a fragmentary view in longitudinal section on the line 3-55 of Figure 2.

l represents the keel of my improved hull having' av shoe 2 thereon, the sides of the keel being recessed, as shown at 3, to receive the bottom planks t which are straight but which incline upwardly from the keel to the sides of the hull.

5 represents the bottom ribs to which the planks 4L are secured and which are also straight and extend from the keel to the sides of the hull. 6 represents the chimes which are located at the sides and bottom of the hull, and 71 are side ribs which are located at rightangles to the bottom ribs 5, and 8 are the frames which are also located at right angles to the bottom ribs 5. 9 indicates the side planking which is secured to the ribs 7 and frames 8 and are perfectly straight and are at right angles to the planking,` 4.

Gn the outside of the hull, at the lower edges thereof, I preferably provide cushioning bars 10, which extend substantially throughout the length of the hull.

1926. Serial No. 107,424.

By reason of this construction, whereby the bottom and side ribs and planking are at right angles to vone another, the side walls of the hull are inclined or tapered inwardly from their lower to their upper ends.

By reason of this construction I am enabled to employ absolutely straight pieces, requiring no bending, curving or cutting of any sort other than cutting them into proper lengths. I am, therefore, enabled to build a. hull much cheaper than is possible with hulls as heretofore made, and I provide a hull of a differentshape from anything heretofore known. I, therefore, do not wish to be limited to the particular constructionV or to other features of the hull but desire to cover broadly this novel construction and arrangement of ribs, planking and frames.

Various slight changes and alterations might be made in the general form 'of the parts described without departing from the invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A hull, comprising a keel, bottom ribs extending upwardly at an angle to the keel and from both sides thereof, side ribs located at right angles to the bottom ribs, and straight planks secured to the bottom ribs and to the side ribs forming the hull.

2. A hull of the character described, hav ing' its sides taperingl inwardly from their lower to their upper ends, the hull having bottom ribs, side ribs and frames located at right angles tothe bottom ribs, and straight planks secured to the bottom ribs, side ribs and frames.

3. A hull of the character described, having' its sides tapering inwardly from their lower to their upper ends, the hull having bottom ribs, side ribs and frames located at right angles to the bottom ribs, straight planks secured to the bottom ribs, side ribs and frames, and cushioning' bars secured to the lower corners of the hull.
